Title: Production of parts from powder
Inventor: FUJITA KATSUYUKI
IPC: B22F3/02
Filed: 1992-11-05
Abstract: PURPOSE:To facilitate the production of a compacted product free from weld lines, shrinkage or the like and die production and to prolong the service life of dies by subjecting molded parts subjected to injection molding to final compacting by vibration compacting. CONSTITUTION:The powder of ceramics or metal is added with an organic binder and is thereafter subjected to injection molding into a molding (material 3) having a thin sheet shape or a blocky shape. This is clamped by an upper die 2 and a lower die 4, and after that, the material 3 is clamped by an upper punch 1 and a lower punch 5. Next, while being synchronized with the upper punch 1 and the lower punch 5, they are vibrated up and down and is compacted into a desired shape. The obtd. green compact is subjected to dewaxing treatment to remove the binder, and after being sintered, it is subjected to finish working to obtain the objective parts. Since the injection molding die molds a simple molded product, its structure is simple. By this injection molding, the voids in the completed parts can be reduced, and the dimensional accuracy can be improved. Furthermore, since the vibration compacting die requires no mechanism of a spool, runner, gate or the like and it is used under low pressure as well, it can be miniaturized and its production is easy.

Title: Zero-cross detection circuit
Inventor: FUJII MICHIO
IPC: G11B19/20
Filed: 1993-11-01
Abstract: PURPOSE:To detect an accurate zero-cross of an input signal by generating a detection signal with an AND between both outputs of a hysteresis comparator with a threshold value in front and rear of a zero detection level receiving the input signal and a regular comparator. CONSTITUTION:A Schmitt circuit 1 having hysteresis characteristic outputs an H and an L when the input signal Vin exceeds the threshold values VTH1 and VTH2. On the other hand, when the signal Vin becomes a zero level or below and or above again, the comparator 2 output H and an L, and generates a pulse according to a noise. Thus, an FF circuit 4 is reset in the fall (the rise of the comparator 2) of a two-input NAND gate 3, and is set in the fall of the circuit 1. Then, the circuit 4 generates a zero-cross detection pulse (d) generating a zero-cross detection edge at a delay time (t) of the gate 3, etc. Thus, the zero-cross point is detected accurately even in the input signal with a relatively higher frequency.

Filed: 1987-11-27
Abstract: PURPOSE:To obtain a semiconductor laser on an Si substrate having low threshold value for continuously oscillating at a room temperature with stable lateral mode by providing an Si N-I-P-I doping superlattice layer on the substrate, and forming its center by impurity diffusing or ion implanting in the same conductivity type as that of the substrate as an internal current narrowing layer. CONSTITUTION:An Si doping superlattice layer is provided on an Si substrate, and an impurity is diffused or ion implanted to form an internal current narrowing layer. That is, the Si doping superlattice layer is operated as an effective buffer layer for alleviating a strain or a stress in case of laminating a GaAsP/GaP distortion superlattice layer on the substrate. When an N-I-P-I Si doping superlattice layer 2 is employed, carrier mobility can be sufficiently reduced in a laminating direction. Accordingly, even if the thickness of the layer is 0.2-0.3mum, it can be operated as a sufficient current narrowing layer. That is, it can be oscillated with a threshold value of 50mAngstrom  or less in a stable basic lateral mode.
